The solution is therefore acidic - it Has pH < 7.00 . Such a structure arises from the need for a refined geometry of atoms necessary for electrons to pair up and thus, form different chemical bonds, as inducted by the valence bond theory. Even Nitrogen, which needs 8 electrons in the valence shell has all 8 of them, thereby forming a full exterior shell. The pH is determined by the hydrolysis of the C2H3O2^- ion and that would be the same for both solutions; i.e., Kb for C2H3O2^- is the same for both. So, the equation for Ka is Ka= [H+] [NH3]/ [NH4+] - we will leave the NO3- ion out of it, since it doesn't participate in the acid/base equilibrium. This means that NH4+ has 4 pairs in total, which are bonded due to the 4 atoms of hydrogen. than CN is a base. HAsO 4 2- 3.210 -12.
